“…Because of its high sugar content, it accelerated the decomposition of organic matter in soil [ 3 , 20 ]. Pressmud is a good source of organic manure that may be utilized to improve soil fertility and crop productivity [ 17 , 21 , 22 ]. It requires more storage space in addition to proper disposal.…”

“…Pressmud is a rejected sugarcane waste that, when accumulated, causes storage issues as well as pollution in the surrounding areas of the sugar mill [ 15 ]. It is a soft, spongy, amorphous, dark brown to brownish material formed as a byproduct of the sugarcane industry during the carbonation or sulphitation of sugar [ 16 , 17 ]. Madhya Pradesh state is having three large scale sugar industries at Indore, producing significant amount of pressmud.…”

“…The organic matter and sugar content are eaten by soil biota as food [ 22 ]. The mineralization of pressmud produces a range of organic acids during decomposition and ions that form complex bonds to adsorb toxic metal ions [ 17 , 23 ]. As a result, PM could be used to treat soils that have been contaminated with lead.…”

Soil fertility management and crop productivity both are inter-related need extensive attention for sustainability. Industries are being built, which over time produces a lot of effluents containing heavy metal(s), which is then dumped on healthy soils and water bodies. Long-term discharge of lead (Pb)-containing wastewater resulted in significant Pb buildup as well as a decrease in soil biological activity. In this experiment, graded dose of Pb, i.e. 0, 100, 150 and 300 mg/kg and pressmud (PM) (0, 2.5, 5, 10 g/kg) were applied to monitor the Pb toxic effect on soil acid and alkaline phosphatase, dehydrogenase activity. Different treatment combinations were formulated and the experiment was conducted in a completely randomized design (CRD) with three replications. In this experiment, spinach crop was used as a test crop. According to the findings, increased Pb levels in the soil lowered dehydrogenase activity (DHA), acid and alkaline phosphatase. The addition of PM enhanced enzymatic activities by decreasing the labile fraction of Pb in the soil. Incorporation of PM improved the soil enzymatic activities as alkaline phosphatase activity > DHA > acid phosphatase activity in the study. This study suggested that the addition of 10 g/kg PM reduced Pb toxicity (contamination level 300 mg/kg) and improved the soil microbial properties in black soil. These findings are very useful for the remediation of Pb contaminated soil with the help of PM, particularly in peri-urban Pb effluent irrigated areas.
